The letters written by Jackson are filed after the letters to him. These were collected by Naomi Jackson Groves from various sources, including his family.

Letters to his brother Ernest describe his working life in Montreal and Chicago 1904-1906. Letters to his mother, sister Kate and brother William describe his experiences travelling, studying and painting in France 1905, 1909, 1912. There is a postcard to James MacCallum from British Columbia 1914, proposing a sketching trip with Tom Thomson, and a letter to Ernest from Algonquin Park. A letter to his [cousin Jack Beck] [1915] describes his feelings about the First World War, as do letters to his mother and sister Kate. A letter [1918] to [James MacCallum] discusses the Canadian War Records programme. A 1920 letter to Kate proposes shipping paintings by Albert Robinson, Robert Pilot and Randolph Hewton from Montreal for a Toronto exhibition. There are many letters to Jackson's mother, Georgina Jackson, and to his brother H.A.C. Jackson and sister-in-law Coralie Jackson. There are extensive letters from Jackson to his cousin Florence Clement, including some illustrated ones, documenting a lifelong affectionate relationship.
